Timney tuned this Impact trigger (brand part number ARPCC) specifically for AR-platform pistol-caliber carbines, a category where hammer spring weight and reset often need different tuning than a standard 5.56 rifle trigger. It’s machined from billet steel with a curved blade and set to a 3-4 pound pull, installing on small-pin, mil-spec-compatible AR-15 lowers using the rifle’s original hammer and trigger pins. As a drop-in unit, it swaps in without any fitting, giving a PCC build a lighter, more consistent pull tuned for the platform it’s actually going into.
